The first two of the following three points are covered in Part A talking about what it is best or right to do. The third point is covered in Part B talking about correcting people.①Shoud/Ought to is used to make suggestions about what it is best to do②Should/Ought to is used to express our strong belief that something is right and is our duty③should/ought to is used to correct errors and to say what is correct2Should and ought to are modal verbs and do not take verbal endings. Remind students that oughted is an impossible form, as this is rather a common mistake.3By learning the form as ought to, students are less likely to get confused about whether to use a to infinitive or a bare infinitive.4Ask students the following questions. Tell them to reply in full sentences. Possible answers have been given in brackets.1 What should we do if we want to get high marks? (We should work hard.)2 What ought we to do if we find a purse on the classroom floor? ( We ought to take it to the teacher.)3 How should we treat our parents when they are old? (We should look after them.)4 How should table be spelled? ( It should be spelled t-a-b-l-e.)5 He are fat is wrong. What ought we to say? ( We ought to say he is fat.)5Read the examples in the pictures with the class, explaining that a typewriter and a cooker are machines, not people.While-reading procedure1Language focusshould和ought to都是情态动词，常用来提供或征求意见，或表达说话者认为应该做的事，意思为“应该”、“应当”。

1．“should/ought to＋动词原形”表示应该做某事，或做某事的动机是正确的。

如：Tom should go to bed earlier. He goes to bed very late and he‟s always tired. 汤姆应该早点睡觉。

他很晚睡觉，总是觉得很累。

It‟s a very nice film. You ought to go and see it. 这是部很不错的电影。

值得一看。

“shouldn‟t（＝should not）／oughtn‟t to（＝ought not to）＋动词原形”表示不该做某事，或做某事的动机是错误的。

如：Tom shouldn‟t go to bed so late. 汤姆不该这么晚才睡觉。

You watch TV all the time. You oughtn‟t to watch TV so much. 你一直在看电视。

你电视不该看这么多。

should和ought to用在疑问句中时，常用来询问他人的见解或建议。

如：— Ought I to finish my homework now? 我应该现在就把作业做完吗？— Yes, you ought to. 是的，应该的。

When should I leave home tomorrow? 我明天应该几点从家里出发？2．should意为“应该”，多用于劝说他人的错误行为或给予他人一些建议，不具备强制力；而must意为“必须”，用于规定或约束他人的行为，具有强制力。

试比较：You shouldn‟t be cruel to animals. 你不该虐待动物。

（不具备强制力）You mustn‟t park your car here. Drive it away immediately. 你不可以把车停在这里，立即开走。

（具有强制力）3．should和ought to常用动词think连用。

如：1）I think … should/ought to …，如：I think Carol should buy some new clothes. 我认为卡罗尔该买些新衣服了。

It‟s late. I think I ought to go home now. 不早了。

我想我该回家了。

2）I don‟t think … should/ought to …，如：I don‟t think you should work so hard. 我认为你无需如此卖力。

I don‟t think we ought to go yet. It‟s too early. 我认为我们没必要这么早走。

时间早着呢。

3）Do you think … should/ought to …?，如：Do you think I should buy that hat? 你认为我们该买那顶帽子吗？What time do you think we should go home? 你觉得我们应该何时回家？2Ask the class to do Exercise A and B.
